TIRE AND Application led June 16,

This invention relates to an improved automobile tire and rim tool andit has reference to 'an article of this kind which is especially, butnot necessarily, adapted for 6 the removing of the usual split band orrirg which is used in association with wheels.

Briefly, the tool is composed of two parts; the first of which is in theform of a lever 10 adapted to be operated by the person doing the work,this lever being constructed to engage and separate the split ends ofthe removable band; together with an adjustable anchoring device formaintaining the leverA in operating position. Y

My principal aim is to provide an exceptionally simple and inexpensivetool of this class, which is highly practical, compact and convenient,and thoroughly reliable under all conditions. Otherobjects andadvantages of the invention will become apparent from the followingdescription and drawings.

In the accompanying drawings forming a part of this-application, and inwhich llke numerals are employed to designate like parts throughout thesame Figure 1 is a view in elevation and section showing the completetool as it is used. Fig. 2 is a view somewhat similar to Fig. 1,tshowing a further step in the operation of the tool.

Fig. 3 is a detail view with portions broken away and shown in sectionto disclose the details more plainly. I

Fig. 4 is a perspective view of one end of the bracing or anchoring arm.Referring to the drawings in detail, the reference character 1designates a tire, the '40 reference character 2 the disk whee'l whichis provided with the usual rim, the reference character 3 designates themovable slit band which is emplo ed in connection with the rim and tire,4 esignates the enlarged central hub opening, and 5 the bolt holes whichsurround this opening.

The improved tool, comprises, as before stated, a lever' which is hereshown as provided with a reduced portion 7 terminating in a hook '8which is ada ted to'engage the slit over-lapped end of t e removableband 3. The' anchoring device, which acts somewhat asa prop, isrepresented generally by the ret'erence c aracter 9 and this comprises`with sai-d downturned en am moor...

me. serial no. 116,430.

A retaining nut 13 is employed for maintaining the parts in ad'ustedposition.'

It will be notice particularly from Fig. 4, that the part 12 terminatesin a downturned or curved end 14, adjacent which areoutstanding stoppins 15. In practice, the downturned end 14 of the part 12 is insertedinto one of the bolt holes 5 adjacent the main central opening 4 in thedisk wheel. Then the screw 10,1s properly adjusted to produce thedeslred leverage. Next, the hooked end Sis en aged beneath the Splitends of the expansi le band 3 and these ends are pryed apart and thenback by swinging the lever as lndicated in Fig. 2, the band is liftedof, thus facilitating removal of the tire.

The advantages, construction, and operation are plainly evident `fromthe description and drawings, and a more lengthy description is-thoughtunnecessary.

Minor changes comin within the field of invention claimed may e resortedto if desired.v

Having thus described my invention, what I claim as new is 1. A tire andrim tool of the class described comprising a lever having a reducedhooked end, and a bracing prop therefore, said prop comprising a screwpivotally connected to the reduced end of the lever, a part into whichsaid screw is threaded, a retaining nut in said screw cooperable withsaid part, said part terminating in a downturned end adapted to t into abolt hole in a disk whee'l, and there being stop ins associated d) forresting lagainst the disk.

2. A tire and rim tool of the class described comprising a lever havinga -hooked end, and a bracing prop therefor, said pro comprisin a pair ofadjustably connecte arts one o whlch is pivotally engaged wit anintermediate portion of the lever and the other of which terminates in alaterall i' extending end adapted to fit into a bolt hole in a diskwhee'l, and there being stop pins associated with said laterallyextendin end for resting against the disk of the dis wheel.

Inv testimony whereof I affix my signature.

, ROY H. HATFIELD.
